You have to do the following MOD first.

Bumper Lens Re-Wire w/pics Found Here - How To's Lights/Lighting

During Step 12 when doing the above Mod, the 8 Watt Wire connected to the side marker lens wire and ---> Cut the other Black Wire (since there are only two) on the side marker lens and connect it to the 27 Watt lens wire in Step 10, (Green wire with Black Tracers - Driver Side & Green wire with Orange Tracer - Passenger Side) on the bumper lens side.

Do all this when everything else works first. This is an additional 2 second job. Therefore, during signal, both lights will alternate which I found it to be much better than only the front bumper blinking during the signal.

Again, do all this at your risk. Thanks to my friend Chet who gave me the above idea.

 

Maybe a Mod needs to move this to in "How To's"

 

I'm not even sure what the original point was. To do both mods?

 

or you just follow these instructions

without changing 1156 to 1157s

 

1st mod is to have BOTH lights ON when parking lights are ON. 2nd mod is to alternate flashing pattern during signal!

 

i did both mods and by far the nicest nighttime mod for me. there are 4 separate lenses on the bumper, why not make use of them all? I'd recommend this to everyone, and also to use a decent 1157 socket when doing the blinker mod, it'll make the job a lot easier.
